FIRE-EXTINGUISH'ING APPARATUS.

SPECIFICATIQN forming part of Letters Patent No. 314,887, dated Miami: 31, 1885.

Application'filed Marthe, 1885. (a; model.)

To all whom it may concern:

Be it known that I, JAMnsR. SMITH, of Chicago, in the county of Cook and State of Illinois. have invented a new and useful Fire- Extinguishing Apparatus; and I do hereby declare that the following is a full, clear, and exact descri tion thereof.

My invention has reference to vessels designed to hold fluids which are to be forced out by means of a pump, and is preferably used as a fire-extinguisher. I do not wish to be limited to such use. I

My invention consists in a novel and convenient arrangement of a vessel for holding a I5 fire-extinguishing or other fluid, provided with one or more adjacent pockets or recepta cles for holding additional charges of the chemical compound to be used when the fluid in the vessel proper is exhausted; also provided with a separate compartment or receptacle for holding a pump, when not in use, separate and apart from the corrosive effects of the chemical fluid, and also provided with an opening in its top through which to insert the pump when necessary to discharge the fluid into the fire. By means of one or more springs provided with lugs and attached to the pump, and of one or more suitable openings in the mouth of the tank for the insertion 0 of the lugs, into which they will work automatically, the pump is securely fastened to the vessel when in use, and can be readily detached when necessaryto withdraw the pump. Usually, when it requires a pump to force the 5 fire-extinguishing liquidinto the firethepump is attached to the vessel containing the liquid, and most often is a part of the apparatus itself. In such cases the pump remains in contact with the acids of the liquid, which corrode it, and in time render it unfit for use in case of a fire. In the prior constructions which have separate pumps not normally in contact with the chemical solution the pump is provided with some stirrup attachment, making 5 it capable of easy use by one person for other purposes, while my means of attaching and operating the pump in this apparatus renders it incapable of use by one person for other purposes, for while one hand operates the pump another holds the pump against the suction of the piston, and another hand is required to direct the lioze or nozzle. By my invention, while the pump is always with the apparatus, unless it is purposely removed, still it is kept out of the corrosive acids until desired for use, and when desired for use is. conveniently at hand.

In the accompanying drawings, Figure 1 shows my device ready for transporation to the fire, and with the side partially broken away to show one ofthe cans containing the dry chemical compound in one of the adjacent pockets. Fig. 2 shows a Vertical section of the same with the pump inserted in the vessel for use.

T is the tank or vessel designed to hold the fire-extinguishing or other liquid. I

B'B are pockets made to hold cans I; b,containing extra charges of the chemical compound, to be used when the contents of the tank are exhausted. Dry chemical compounds may be transported loosely in these pockets, being inclosed therein with a stopple or atop, without the necessity of the extra cans.

G is a separate chamber made to hold the pump P. Any ordinary syringe or pump provided with suitable hose and of the proper dimensions can be used.

S S are springsv securely attached to the sides of the pump, provided with lugsllto fit into the openings 0 O in the mouth of the tank, one or more of which can be used.

The apparatus can be transported by a handle or strap to fit the shoulders of the party carrying it. 8 5

When out of use, the pump is to be placed in the chamber 0, where it is out of the way and in convenient position for transportation, and is not subject to corrosive effects of the acid if left in contact therewith in the same 0 vessel containing the fire-extinguishing liquid.

By having the springs on the pump provided with lugs to fit in the openings 0 in the mouth of the tank, or with some similar device to securely fasten the pump to the tank while in 5 use, one man can easily use the apparatus.

To this end I do not wish to be confined to the peculiar means shown to fasten the pump into the tank when in use. Any suitable means may be used. 10o

If desirable, stirrups can be attached to the apparatus, on which the operator can place his feet when using the apparatus.

When necessary to use the fire-extinguishing liquid, the mouth of the tank is opened, the pump placed therein and secured to the tank by means of the springs and lugs working into the openings 0, or by some other suitable means, and is then ready for use. Should the contents of the tank be exhausted,

the chemical compound can be separated from the extra charges in the vessels in the pockets, and by the addition of water the contents will be again ready for use. One or more of these pockets can be used, as desired. This tank and the vessels containing the extra charges of the fire-extinguishing liquid, or the pockets themselves, if used without the cans, can be hermetically sealed, it the liquid is of such nature as that it will evaporate if exposed to the air; or they can be used with ordinary caps or any convenient stopples should the liquid be of such nature as that it does not require to be hermetically sealed.

Having thus described my invention, I claim and desire to secure by Letters Patent .ing of a vessel or tank provided with one or more openings, 0 O, in its mouth, in combination with a pump provided with one or more springs, with lugs arranged to fit into said openings, substantially as and for the purposes shown.

JAMES B. SMITH.
